Folks

Quite a few people have asked for splices in Template Haskell *types*, and I have finally gotten around to implementing them. So now you can write things like

       instance Binary $(blah blah) where ...
or      f :: $(wubble bubble) -> Int

Great! Just what I was looking for a couple of days ago.

PS: Note that you (still) cannot write a splice in a *binding* position.

I think, I can live without it.
